I feel capable of putting them in once I have them but am not sure exactly what I need to buy (someone told me the original values are no longer available so I have to get the nearest value to the originals). I have been looking at http://www.cricklewoodelectronics.co...me.php?cat=162 but there are so many different types I am stumped Could anyone advise what I need? Thankyou.
I would hesitate to stuff the can with 3 separate caps unless I could guarantee the replacements could handle the ripple current. Most replacement axial lead electros will not have the ripple handling capacity of the original can.
Unfortunately I have seen the results of under-rated caps used in this situation ( but not by me) - a fire tends to focus the mind .

On the bright side, you can still get multi-section can types - 2 in 1, 3 in 1 and even 4 in 1. Antique Electronic Supply in USA carry a good selection but be warned - they are not cheap. See http://www.tubesandmore.com/. Search on C-EC as this is the part number prefix for all their multi-section caps.

Also try http://www.askjanfirst.com/eindex.htm
They have a good selection of multi-section caps but maybe not 3 in 1.

Cheers

Mike
